Project Session Manager (PSM) Skill

psm is the compatibility alias for this canonical skill entrypoint.

Quick Start (worktree-first): Start with omc teleport when you want an isolated issue/PR/feature worktree before adding any tmux/session orchestration:

omc teleport #123          # Create worktree for issue/PR
omc teleport my-feature    # Create worktree for feature
omc teleport list          # List worktrees

See Teleport Command below for details.

Automate isolated development environments using git worktrees and tmux sessions with Claude Code. Enables parallel work across multiple tasks, projects, and repositories.

Canonical slash command: /oh-my-claudecode:project-session-manager (alias: /oh-my-claudecode:psm).

Commands

Project References

Supported formats:

  • Alias: omc#123 (requires ~/.psm/projects.json)
  • Full: owner/repo#123
  • URL: https://github.com/owner/repo/pull/123
  • Current: #123 (uses current directory's repo)

Configuration

Project Aliases (~/.psm/projects.json)

{
  "aliases": {
    "omc": {
      "repo": "Yeachan-Heo/oh-my-claudecode",
      "local": "~/Workspace/oh-my-claudecode",
      "default_base": "main"
    }
  },
  "defaults": {
    "worktree_root": "~/.psm/worktrees",
    "cleanup_after_days": 14
  }
}

Providers

PSM supports multiple issue tracking providers:

ProviderCLI RequiredReference FormatsCommands
GitHub (default)ghowner/repo#123, alias#123, GitHub URLsreview, fix, feature
JirajiraPROJ-123 (if PROJ configured), alias#123fix, feature

Jira Configuration

To use Jira, add an alias with jira_project and provider: "jira":

{
  "aliases": {
    "mywork": {
      "jira_project": "MYPROJ",
      "repo": "mycompany/my-project",
      "local": "~/Workspace/my-project",
      "default_base": "develop",
      "provider": "jira"
    }
  }
}

Important: The repo field is still required for cloning the git repository. Jira tracks issues, but you work in a git repo.

For non-GitHub repos, use clone_url instead:

{
  "aliases": {
    "private": {
      "jira_project": "PRIV",
      "clone_url": "[email protected]:team/repo.git",
      "local": "~/Workspace/repo",
      "provider": "jira"
    }
  }
}

Jira Reference Detection

PSM only recognizes PROJ-123 format as Jira when PROJ is explicitly configured as a jira_project in your aliases. This prevents false positives from branch names like FIX-123.

Jira Examples

# Fix a Jira issue (MYPROJ must be configured)
psm fix MYPROJ-123

# Fix using alias (recommended)
psm fix mywork#123

# Feature development (works same as GitHub)
psm feature mywork add-webhooks

# Note: 'psm review' is not supported for Jira (no PR concept)
# Use 'psm fix' for Jira issues

Jira CLI Setup

Install the Jira CLI:

# macOS
brew install ankitpokhrel/jira-cli/jira-cli

# Linux
# See: https://github.com/ankitpokhrel/jira-cli#installation

# Configure (interactive)
jira init

The Jira CLI handles authentication separately from PSM.

Session Naming

The public session ID (colon form, e.g. omc:pr-123) is the human-facing identifier stored in sessions.json and used with psm attach/psm kill. tmux reserves : and . for its session:window.pane target syntax and silently rewrites them, so the actual tmux session name uses a tmux-safe form where those characters become _ (issue #3528). PSM translates the public ID to the tmux-safe name at every tmux boundary; attach directly with the tmux-safe name.

Implementation Protocol

When the user invokes a PSM command, follow this protocol:

Parse Arguments

Parse {{ARGUMENTS}} to determine:

  1. Subcommand: review, fix, feature, list, attach, kill, cleanup, status
  2. Reference: project#number, URL, or session ID
  3. Options: --branch, --base, --no-claude, --no-tmux, etc.

Subcommand: review <ref>

Purpose: Create PR review session

Steps:

  1. Resolve reference:

    # Read project aliases
    cat ~/.psm/projects.json 2>/dev/null || echo '{"aliases":{}}'
    
    # Parse ref format: alias#num, owner/repo#num, or URL
    # Extract: project_alias, repo (owner/repo), pr_number, local_path
    
  2. Fetch PR info:

    gh pr view <pr_number> --repo <repo> --json number,title,author,headRefName,baseRefName,body,files,url
    
  3. Ensure local repo exists:

    # If local path doesn't exist, clone
    if [[ ! -d "$local_path" ]]; then
      git clone "https://github.com/$repo.git" "$local_path"
    fi
    
  4. Create worktree:

    worktree_path="$HOME/.psm/worktrees/$project_alias/pr-$pr_number"
    
    # Fetch PR branch
    cd "$local_path"
    git fetch origin "pull/$pr_number/head:pr-$pr_number-review"
    
    # Create worktree
    git worktree add "$worktree_path" "pr-$pr_number-review"
    
  5. Create session metadata:

    cat > "$worktree_path/.psm-session.json" << EOF
    {
      "id": "$project_alias:pr-$pr_number",
      "type": "review",
      "project": "$project_alias",
      "ref": "pr-$pr_number",
      "branch": "<head_branch>",
      "base": "<base_branch>",
      "created_at": "$(date -Iseconds)",
      "tmux_session": "psm_${project_alias}_pr-$pr_number",
      "worktree_path": "$worktree_path",
      "source_repo": "$local_path",
      "github": {
        "pr_number": $pr_number,
        "pr_title": "<title>",
        "pr_author": "<author>",
        "pr_url": "<url>"
      },
      "state": "active"
    }
    EOF
    
  6. Update sessions registry:

    # Add to ~/.psm/sessions.json
    
  7. Create tmux session (tmux-safe name; :/. are translated to _):

    tmux new-session -d -s "psm_${project_alias}_pr-$pr_number" -c "$worktree_path"
    
  8. Launch Claude Code (unless --no-claude):

    # --dangerously-skip-permissions prevents the "Do you trust this directory?" prompt
    # and repeated tool-approval prompts from stalling the session (issue #2508).
    tmux send-keys -t "psm_${project_alias}_pr-$pr_number" "claude --dangerously-skip-permissions" Enter
    
    # After claude boots (PSM_CLAUDE_STARTUP_DELAY, default 5s), deliver the task.
    # Use -l (literal) so special characters are not misinterpreted by tmux.
    sleep "${PSM_CLAUDE_STARTUP_DELAY:-5}"
    tmux send-keys -t "psm_${project_alias}_pr-$pr_number" -l \
      "Review PR #$pr_number: \"$pr_title\" by @$pr_author ($head_branch$base_branch). URL: $pr_url." Enter
    
  9. Output session info:

    Session ready!
    
      ID: omc:pr-123
      Worktree: ~/.psm/worktrees/omc/pr-123
      Tmux: psm_omc_pr-123
    
    To attach: tmux attach -t psm_omc_pr-123   (or: psm attach omc:pr-123)
    

Subcommand: fix <ref>

Purpose: Create issue fix session

Steps:

  1. Resolve reference (same as review)

  2. Fetch issue info:

    gh issue view <issue_number> --repo <repo> --json number,title,body,labels,url
    
  3. Create feature branch:

    cd "$local_path"
    git fetch origin main
    branch_name="fix/$issue_number-$(echo "$title" | tr ' ' '-' | tr '[:upper:]' '[:lower:]' | head -c 30)"
    git checkout -b "$branch_name" origin/main
    
  4. Create worktree:

    worktree_path="$HOME/.psm/worktrees/$project_alias/issue-$issue_number"
    git worktree add "$worktree_path" "$branch_name"
    
  5. Create session metadata (similar to review, type="fix")

  6. Update registry, create tmux, launch claude: Same as review, but pass issue context as the initial task prompt:

    tmux send-keys -t "psm_${project_alias}_issue-$issue_number" "claude --dangerously-skip-permissions" Enter
    # After claude boots, deliver the task (see PSM_CLAUDE_STARTUP_DELAY):
    tmux send-keys -t "psm_${project_alias}_issue-$issue_number" -l \
      "Fix issue #$issue_number: \"$issue_title\". URL: $issue_url. Branch: $branch_name." Enter
    

Subcommand: feature <project> <name>

Purpose: Start feature development

Steps:

  1. Resolve project (from alias or path)

  2. Create feature branch:

    cd "$local_path"
    git fetch origin main
    branch_name="feature/$feature_name"
    git checkout -b "$branch_name" origin/main
    
  3. Create worktree:

    worktree_path="$HOME/.psm/worktrees/$project_alias/feat-$feature_name"
    git worktree add "$worktree_path" "$branch_name"
    
  4. Create session, tmux, launch claude with feature context as initial prompt:

    tmux send-keys -t "psm_${project_alias}_feat-$feature_name" "claude --dangerously-skip-permissions" Enter
    tmux send-keys -t "psm_${project_alias}_feat-$feature_name" -l \
      "Implement feature \"$feature_name\" for project $project. Branch: $branch_name." Enter
    

Subcommand: list [project]

Purpose: List active sessions

Steps:

  1. Read sessions registry:

    cat ~/.psm/sessions.json 2>/dev/null || echo '{"sessions":{}}'
    
  2. Check tmux sessions:

    tmux list-sessions -F "#{session_name}" 2>/dev/null | grep "^psm_"
    
  3. Check worktrees:

    ls -la ~/.psm/worktrees/*/ 2>/dev/null
    
  4. Format output:

    Active PSM Sessions:
    
    ID                 | Type    | Status   | Worktree
    -------------------|---------|----------|---------------------------
    omc:pr-123        | review  | active   | ~/.psm/worktrees/omc/pr-123
    omc:issue-42      | fix     | detached | ~/.psm/worktrees/omc/issue-42
    

Subcommand: attach <session>

Purpose: Attach to existing session

Steps:

  1. Parse session ID: project:type-number

  2. Verify session exists:

    tmux has-session -t "psm_${session_id//[.:]/_}" 2>/dev/null   # translate public id to tmux-safe name
    
  3. Attach:

    tmux attach -t "psm_${session_id//[.:]/_}"
    

Subcommand: kill <session>

Purpose: Kill session and cleanup

Steps:

  1. Kill tmux session:

    tmux kill-session -t "psm_${session_id//[.:]/_}" 2>/dev/null
    
  2. Remove worktree:

    worktree_path=$(jq -r ".sessions[\"$session_id\"].worktree" ~/.psm/sessions.json)
    source_repo=$(jq -r ".sessions[\"$session_id\"].source_repo" ~/.psm/sessions.json)
    
    cd "$source_repo"
    git worktree remove "$worktree_path" --force
    
  3. Update registry:

    # Remove from sessions.json
    

Subcommand: cleanup

Purpose: Clean up merged PRs and closed issues

Steps:

  1. Read all sessions

  2. For each PR session, check if merged:

    gh pr view <pr_number> --repo <repo> --json merged,state
    
  3. For each issue session, check if closed:

    gh issue view <issue_number> --repo <repo> --json closed,state
    
  4. Clean up merged/closed sessions:

    • Kill tmux session
    • Remove worktree
    • Update registry
  5. Report:

    Cleanup complete:
      Removed: omc:pr-123 (merged)
      Removed: omc:issue-42 (closed)
      Kept: omc:feat-auth (active)
    

Subcommand: status

Purpose: Show current session info

Steps:

  1. Detect current session from tmux or cwd:

    tmux display-message -p "#{session_name}" 2>/dev/null
    # or check if cwd is inside a worktree
    
  2. Read session metadata:

    cat .psm-session.json 2>/dev/null
    
  3. Show status:

    Current Session: omc:pr-123
    Type: review
    PR: #123 - Add webhook support
    Branch: feature/webhooks
    Created: 2 hours ago

Teleport Command

The omc teleport command provides a lightweight alternative to full PSM sessions. It creates git worktrees without tmux session management — ideal for quick, isolated development.

Usage

# Create worktree for an issue or PR
omc teleport #123
omc teleport owner/repo#123
omc teleport https://github.com/owner/repo/issues/42

# Create worktree for a feature
omc teleport my-feature

# List existing worktrees
omc teleport list

# Remove a worktree
omc teleport remove issue/my-repo-123
omc teleport remove --force feat/my-repo-my-feature

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

agent-doc-discipline

Writing-time discipline for documents agents consume (the five surfaces, specs, tickets, .omc/skills/) — every rule checkable and carrying a why, steps before reference, one meaning in one home, no restating what the environment already says. Mandatory at drydock seed generation and the launch C5 sediment pass; opt-in for any other agent-facing doc edit. The companion of minimal-code-discipline: that one disciplines code, this one disciplines papers.

ai-slop-cleaner

Clean AI-generated code slop with a regression-safe, deletion-first workflow and optional reviewer-only mode

ask

Process-first advisor routing for Claude, Codex, Gemini, Antigravity, Grok, or Cursor via `omc ask`, with artifact capture and no raw CLI assembly

ask-navigator

Shipyard

autopilot

Full autonomous execution from idea to working code

autoresearch

Stateful single-mission improvement loop with strict evaluator contract, markdown decision logs, and max-runtime stop behavior

cancel

Cancel any active OMC mode (autopilot, ralph, ultragoal, swarm, ultrapilot, pipeline, team) and clean up retired legacy state

configure-notifications

Configure notification integrations (Telegram, Discord, Slack) via natural language

debug

Diagnose the current OMC session or repo state using logs, traces, state, and focused reproduction

deepinit

Deep codebase initialization with hierarchical AGENTS.md documentation

deep-interview

Socratic deep interview with mathematical ambiguity gating before explicit execution approval

drydock

Lay the keel of the shipyard harness in any repo — the 4-pillar shared environment (Context, Rules, Tools, Standards) across 5 surfaces (CLAUDE.md, skills, design-system, mcp/cli, shared context) so that every human and agent inherits the same design language and anyone can ship. Run once per repo; re-run with --check to audit drift.

execute

Carry an approved task through to working, verified code

external-context

Invoke parallel document-specialist agents for external web searches and documentation lookup

graph

Deterministic orchestration graph runtime - declarative DAG pipelines with journal-based crash recovery

harbor

Harbor intake for external work — the captain only handles unresolved decisions. Sweeps incoming issues and PRs, verifies every claim before disposition, reuses every decision already made, and hands the maintainer a docket whose pending items each carry one question with options, recommendation, impact and evidence. Agent-autonomous for facts and for actions covered by standing authorization; signed for every new judgment. Never merges.

hud

Configure HUD display options (layout, presets, display elements)

launch

Shipyard

loft

Loft the shape before cutting steel — answer a design question that prose cannot settle by building a throwaway artifact: a pure logic module in a clickable shell, or structurally different UI variants behind one route. The captain reacts to the artifact; the answer folds into the decision; the artifact never docks. Use when a design question stalls in words, when a navigator map carries a loft ticket, or when a spec discussion reaches

minimal-code-discipline

YAGNI-ladder coding discipline for writing changes — existence-first, reuse before writing, dependency ladder, shortest correct diff, with non-negotiables that must never be minimized away
